Steven Mayo, 22, of Dover-Foxcroft was indicted last month on charges of murder and depraved indifference murder, both Class A crimes, in the death of his brother Ryan Mayo, 20. If convicted, Mayo could serve up to 30 years on each count.

According to a state police affidavit, Steven Mayo told police that he had returned home from grocery shopping on May 1 and found his driveway torn up from an all-terrain vehicle. He said he walked to his brother’s home next door and began removing fuses from the vehicle, which was parked on the lawn. He told police that his brother had damaged his property before despite being told not to do so.

In addition, Mayo told police that Ryan Mayo came out of his house and began chasing him, at one point using a white metal pole to hit Steven Mayo’s truck. Ryan also allegedly hit his brother in the mouth before yelling that he was going to get a gun and “blow Steven’s brains out,” according to the affidavit.

Steven Mayo told police that he went and got a Russian rifle from his house and blew out the tires to his brother’s ATV. Mayo said his brother then came out of his house with a shotgun and fired it. Steven Mayo told police he then shot at Ryan Mayo as he was re-entering his house.

After Mayo’s arraignment on Tuesday, the case was continued 60 days to allow for the filing of motions. Two lawyers — Randy Day of Garland and Marvin Glazier of Bangor — were appointed to represent him.
